Magento form validation only works on the last checkbox in a group

问题

I am using the built-in Magento form validation to ensure the user makes a selection on a particular group of radio boxes.

The code below looks fine however

<div class="input-box">
  <li class="control">
   <input type="radio" class="radio organisation_type" value="1" id="billing:organisation_type_1" name="billing[organisation_type]"> <?php echo $this->__('School') ?></li>
  <li class="control">
   <input type="radio" class="radio organisation_type" value="2" id="billing:organisation_type_2" name="billing[organisation_type]"> <?php echo $this->__('Parent') ?></li>
  <li class="control">
   <input type="radio" class="radio validate-one-required organisation_type" value="3" id="billing:organisation_type_3" name="billing[organisation_type]"> <?php echo $this->__('Business') ?></li>
</div>

I am using the validate-one method on the class on the last radio box

For some reason the code above will only let me proceed if I select the last radio box?? Can anyone explain why if I check either the first or second box the validation is still failing?

回答1:

You need to add validate-one-required-by-name to the last radio button.

<input type='radio' class="validate-one-required-by-name .. "

Take a look at Payment Method when placing an admin order

You can't use the same ID in any case. Make your input id attributes always different.
